How the words-to-numbers converter works
English number names follow a regular pattern, which makes them possible to parse back into digits. This converter reads the words you type, recognises each value word and each scale word, and rebuilds the numeric value. It is the reverse of spelling a number out: instead of going from 1,234 to “one thousand two hundred thirty-four”, it goes from the words back to 1,234.
The parser keeps a running total and a current group value. When it meets a unit or tens word it adds to the current group; when it meets “hundred” it multiplies the group by one hundred; and when it meets a larger scale word like “thousand” or “million”, it multiplies the group by that scale and folds it into the total. Connecting words such as “and” are ignored, and hyphenated forms like “thirty-four” are split automatically.
This is handy when you receive an amount written out — on a cheque, in a contract, in a spoken figure you have transcribed — and you need it as a number for a spreadsheet or form. The conversion runs entirely in your browser, so it is instant and private. For the opposite task, the Number to Words converter turns digits into written English.

Frequently asked questions
How do I convert words to numbers?
Type the number in plain English — for example “two million five hundred thousand” — and the converter parses the words and scale terms into the digit value 2,500,000 instantly.
Which words are understood?
It recognises units (one to nineteen), tens (twenty to ninety), and scale words: hundred, thousand, million, billion and trillion. Hyphens and the word “and” are handled.
Is it accurate for large numbers?
Yes. The parser combines each value with its scale word the way English number naming works, so large compound numbers convert correctly.
